The web listing says "violinist Jennifer Pike and Andrew Manze join the orchestra in Perth for a Vaughan Williams concert". The BBCSSO repeats concerts in Glasgow, Edinburgh & Perth, as do the RSNO & Scottish Chamber Orchestra. They are much more 'national' orchestras than the London-based ones - do they ever tour?
But it is surprising that the repeat is billed as 'from Perth', given that the original live broadcast was from Glasgow.
